How to Make Everything Bagel Make Ahead Breakfast Casserole Recipe

Step 1: Prepare Your Casserole Dish

Start by greasing a 13×9 inch casserole dish thoroughly. This ensures your casserole will release easily after baking and makes cleanup a breeze.

Step 2: Layer Half the Bagel Cubes and Toppings

Add half of the cubed everything bagels evenly to the bottom of the dish. Sprinkle half the cooked, diced bacon over the bagels. Follow by layering half of the shredded Gruyere and then half of the cream cheese cubes. This layering creates bursts of savory flavor in every bite.

Step 3: Repeat Layers

Now, add the remaining bagel cubes on top, then repeat the layering of bacon, Gruyere, and cream cheese. This double layering technique ensures the casserole is rich, cheesy, and perfectly balanced throughout.

Step 4: Whisk Together the Egg Mixture

In a large bowl, combine the eggs, heavy cream, salt, and pepper. Whisk everything together until the mixture is smooth and well blended. This custard will soak into the bagels, making the casserole creamy and moist after baking.

Step 5: Pour Egg Mixture Over Layers

Pour the egg and cream mixture evenly over the layered bagels, making sure it fully covers each piece. This step is crucial for the custard to permeate the entire dish, creating that dreamy texture we all love in a breakfast casserole.

Step 6: Refrigerate for 4 Hours or Overnight

Tightly cover the casserole dish with plastic wrap or foil and place it in the refrigerator for at least 4 hours, or preferably overnight. This resting period lets the bagels soak up the custard, intensifying the flavors and setting the casserole up for perfect baking.

Step 7: Preheat Oven and Prepare for Baking

About an hour before you want to serve, preheat your oven to 350 degrees Fahrenheit. Remove the casserole from the fridge and get ready to bake it to golden perfection.

Step 8: Bake with Foil Cover, Then Uncover

Cover the casserole dish with aluminum foil and bake for 40 minutes. Then, remove the foil and continue baking uncovered for an additional 15 minutes. This helps the top get beautifully browned and slightly crispy while ensuring the inside remains tender.

Step 9: Cool and Garnish

After baking, let the casserole cool for about 10 minutes so it sets up nicely and is easier to cut. Before serving, sprinkle freshly chopped chives over the top for a pop of color and a mild onion flavor that elevates every bite.

Garnishes

Chopped fresh chives are perfect for a fresh, mild onion flavor and a burst of green color that makes the casserole look inviting. You can also add a dollop of sour cream or a drizzle of hollandaise sauce to impress your brunch guests even more.

Side Dishes

This casserole pairs beautifully with fresh fruit salad, roasted potatoes, or a crisp green salad to balance the richness. Freshly brewed coffee or a mimosa makes the meal feel extra special without requiring extra fuss.

Creative Ways to Present

Serve the casserole in a rustic ceramic dish right out of the oven for a cozy, homestyle vibe. Or portion it into individual ramekins for a more elegant presentation. For a festive brunch, garnish with edible flowers or sliced avocado for added color and texture variations.

Make Ahead and Storage

Storing Leftovers

If you have any leftovers, cover them tightly with foil or plastic wrap and store in the refrigerator. The casserole will stay fresh for 3 to 4 days, making for an easy grab-and-go breakfast or snack.

Freezing

This casserole freezes very well! Wrap the entire prepared but unbaked casserole tightly in plastic wrap and then aluminum foil, or transfer portions into freezer-safe containers. Freeze for up to 3 months. Thaw overnight in the refrigerator before baking.

Reheating

Reheat individual portions in the microwave until warmed through, or place the whole casserole in a preheated oven at 325 degrees Fahrenheit covered with foil to prevent drying out. Reheat for about 20 minutes or until warm in the center, then remove foil and bake a few more minutes to crisp the top.

FAQs

Can I use a different type of bagel for this casserole?

Absolutely! While everything bagels provide that iconic seasoning blend, you can substitute plain or sesame bagels if you prefer or have them on hand. Just be mindful that the seasoning impact will change slightly.

Is it possible to make this casserole dairy-free?

You can experiment by using dairy-free cheeses and milk alternatives, but the texture and flavor will be different. The creamy richness of Gruyere and cream cheese is a key part of what makes this casserole so delicious.

Can I prepare this casserole vegan or vegetarian?

For a vegetarian version, simply omit the bacon or replace it with a plant-based bacon substitute. Vegan adaptations are more challenging due to the eggs and dairy but using tofu scrambles and vegan cheeses might work with some tweaks.

How long can the casserole sit in the fridge before baking?

It is best to refrigerate for at least 4 hours, but overnight (up to 24 hours) is ideal to allow the custard to soak in fully and deepen the flavors.

Can I make this casserole gluten-free?

Traditional everything bagels contain gluten, so for a gluten-free casserole, use gluten-free bagels seasoned similarly or toasted gluten-free bread cubes to mimic the texture and taste.
